DEVICE FOR SUPPLYING ELECTRIC POWER TO AN ELECTRICAL MEMBER USING AN ELECTROMAGNETIC RELAY

摘要

The invention concerns a device (10) comprising a first circuit (14) including a first electric power supply source (16) and an electromagnetic relay (18) equipped with a coil (20) controlling the movement of at least one first mobile contact (22) between a rest position (PR) wherein the first source (16) is isolated from the electrical member (12) and an active position (PA) wherein the first source (16) is connected to the electrical member (12). The device (10) further comprises a second circuit (24) including the coil (20) and a second source (26) supplying electric power to the coil (20), imposing a current flowing through the coil (20) of sufficient intensity (ID) to move the first mobile contact (22) from its rest position (PR) towards its active position (PA). Means (30) for reducing the intensity (I) of the current flowing through the coil (20) are activated when the first mobile contact (22) is in active position (PA), the reduced intensity of the current being still sufficient to maintain the first mobile contact (22) in active position (PA).
